Prepare a report about the Unified Modeling Language (UML) and the UML tools. Explain what is the UML and what do the UML diagrams represent?. Provide examples with explanations about the notations and semantics. Make a survey of UML Tools and compare three to five of the most popular/important ones. Make sure you provide references.

UML is as integrated set of diagrams that is used for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems. The UML uses graphical notations to express the design of software projects. Using the UML helps project teams can communicate, explore potential designs, and validate the architectural design of the software. The UML is a foundation of developing object oriented software and the software development process.

Below are the various UML diagrams-
1. Use Case Diagram- Use case diagrams gives an overview of the actors involved in a system, different functions needed by those actors and how these different functions interact.
It has various actors and various use cases which refer to various activities the actors can perform.

2. Class Diagram- Class diagrams are the main building block of any object oriented solution. It shows the classes in a system, attributes, and operations of each class and the relationship between each class.
